Seven other substances were identified as being a part of the Fatty Acids and Derivatives Group at the outset of the third phase of the CMP.

One of the 7 substances (CAS RN 8002-65-1) was originally included in the Draft Screening Assessment for the Fatty Acids and Derivatives Group published on August 18, 2018; however, based on additional information received, this UVCB (Unknown or Variable Composition, Complex Reaction Products or Biological Materials) substance requires further assessment. Therefore, further evaluation of this substance will be provided in a separate screening assessment.

Four of the 7 substances [CAS RNs 68139-89-9, 53980-88-4, 68647-55-2, and Domestic Substances List (DSL) Confidential Accession Number 11556-0] were subsequently determined to be of low concern to both human health and the environment, through other approaches.  Conclusions for CAS RN 68139-89-9 are provided in the Final Screening Assessment for Substances Identified as Being of Low Concern using on the Ecological Risk Classification of Organic Substances and the Threshold of Toxicological Concern (TTC)-based Approach for Certain Substances. Conclusions for CAS RNs 53980-88-4, 68647-55-2, and DSL Confidential Accession Number 11556-0 are provided in the Final Screening Assessment for the Rapid Screening of Substances with Limited General Population Exposure.

The remaining 2 substances (CAS RNs 68476-03-9 and 73138-45-1) were placed into another substance group to which they are more appropriately suited on the basis of scientific considerations. Conclusions for these substances are provided in the Final Screening Assessment for Seven Hydrocarbon-based Substances.
